The Last Avengers: Old Man Logan, Doctor Strange, She-Hulk, Nova, Mania, and Cletus Cassidy(Carnage)
After Mr. Fantastic and Molecule Man take the Beyonder's powers from Dr. Doom, Doom seeks revenge on Earth's mightiest. Using a multiversal "Nexus Navigator," Doom requests the aid of Thanos, wielder of a complete Infinity Gauntlet. Doom offers Thanos advanced technology and support in achieving what he most desires. Thanos obliges with an eerie grin.
Dr. Doom and Thanos, now with armor that matches the likes of Doom's, go out and cause mass amounts of destruction. They eliminate the Guardians of the Galaxy and execute the Shi'ar Imperial Guard before setting their sights on Earth. Before the Guardians where killed, they sent out a distress call to the Nova corps. Doom aids in the creation of technologically sophisticated Sentinels to kill of the Mutants, but Logan was able to escape. Then Doom and Thanos get to Avengers tower and dominate everyone in sight. After realizing there is no hope, Doctor Strange makes the decision to portal himself and the only other Avengers he is able to save, She-Hulk and Mania. The Fantastic 4 arrive to stop the evil duo but Doom is smart enough to know he and Thanos will be able to take them on, he sends the 4 to a different dimension using his Nexus Navigator.
While Doom and Thanos continue their conquering of Earth, Doctor Strange, She-Hulk, and Mania regroup and must come up with a plan to take on Doom and Thanos. Strange suggests the group of 3 alone will be unable to stop the destruction so they seek out other heroes that will aid them. As they are coming up with ideas, Nova prime lands on Earth and finds the trio. On the way there, Nova come across Logan and they set out to recruit him to there cause. Logan, filled with sadness and rage from the loss of his mutant family, he agrees and also suggests they seek out an ally that will have no issue putting their life on the line for a price. Mania brings up prisoner Cletus Kasady. They offer the vessel of the Carnage symbiote freedom and future immunity to have him join them. With that, the teams is set.
The day comes to confront the deadly duo. Logan, She-Hulk, and Mania give their all to take down Thanos. Logan dealing constant damage to Thanos and his armor, She-Hulk uses her immense strength to tire out Thanos while Mania uses her symbiote to get under the Infinity Gauntlet and remove it from Thanos' grasp. Strange, Nova prime, and Carnage try to bring down the Mighty Dr. Doom, inflicting small wounds to Doom. As Doom is about to overcome his oppositions, Thanos was taken down and She-Hulk wielded the Infinity Gauntlet. She uses the powers of the stones to take Doom's Nexus Navigator and opens up multiversal portals to bring back the Fantastic 4 and the heroes of that dimension. Doom is overwhelmed and is killed.
The multiversal heroes return to their dimension and our heroes attend to rebuilding their society. Logan sets out to destroy every Doom Sentinel and hopes to find ant remaining mutants. The fantastic 4 along with Doctor Strange and She-Hulk provide aid to those who suffered through the event. Nova returns to Xandar and begins recruiting members to rebuild the Guardians of the Galaxy. Cletus Kasady embarks of this new chapter of his life of freedom while Mania watches closely behind.
Will the world ever recover from this, and if it does, who will be there to protect it?
